OpenWrt：WRTnode2P實現聯網

登錄WRTnode2P（telnet或ssh）

使用microUSB供電，一頭接在WRTnode2P標準底板的迷你usb接口，一頭接到一個超過500ma的5v供電的地方，上電之後，WRTnode2P底板上的藍燈亮起，裏面的OpenWrt開始啓動了，20秒後就能發現一個WRTnode2P_xxxx（xxxx指WRTnode2P mac地址的後四位）的Wi-Fi，用電腦或手機或ipad連上，密碼是12345678。

首先經過ping openwrt.lan看看連上WRTnode2P沒有，WRTnode2P的IP地址是192.168.8.1，openwrt.lan這個域名會被WRTnode2P攔截並解析到本身的ip地址。

若是第一次登錄WRTnode2P，或者以前沒有給OpenWrt的root用戶設置密碼，那就telnet：

$ telnet 192.168.8.1

或是

$ telnet openwrt.lan

或者已經設置過root密碼了，那就ssh:

$ ssh root@192.168.8.1

或是

$ ssh root@openwrt.lan

aps是WRTnode的自定義命令，掃描當前的Wi-Fi，結果以下所示：

而後將WRTnode2P連上路由器：

# setwifi 鏈接的路由器SSID 對應的密碼

看看WRTnode2P有沒有從上級路由DHCP獲取IP地址:

root@OpenWrt:/# ia
apcli0    Link encap:Ethernet  HWaddr 66:51:7E:00:82:8C  
          inet addr:192.168.0.102  Bcast:192.168.0.255  Mask:255.255.255.0
          inet6 addr: fe80::6451:7eff:fe00:828c/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

          TX packets:83 errors:0 dropped:0 overruns:0 carrier:0

          RX bytes:31804 (31.0 KiB)  TX bytes:6514 (6.3 KiB)

獲取到IP後，看看是否是已經連上互聯網了：

root@OpenWrt:/# ping www.baidu.com
